    The Quadrilateral Trike

    You are aiming high considering you have no workshop and presumably have limited tools too. If your design is done in a quality CAD program you can reasonably farm out some production knowing it will work. If you have more basic sketches then it's likely many parts will be modified as you go...

    Street fox question

    I've used these two before and found them to be within a MM of each other. The last one says it's for ebikes but it really makes zero difference to the result.

    My life with Python trikes Mk1 , Mk1.5 , Mk2 ?

    Those dimensions do pose design issues but you don't yet have them in that prototype yet it is unstable at it's current dimensions. You may learn it's instability and work around it and you may design some instability out. My point is that you choose to start with a known unstable design instead...

    I don't understand your love of all things inherently unstable but I admire your persistence with them.

    Ed's 'StreetRunner' Quad Build

    Did you have the calliper fully bolted up during that? It gives a fair bit with the disc wobble. The inboard drive sprocket has a fair bit of eccentricity too. There's many a time I've tried to make my own alignment on sprockets and I know it's a tough old ask to get 100% when you haven't got...

    Stretched cruiser, sort of.

    I like the bikestand you're using. I can think of several times when I could have used one like that. I'll have to cobble one up.

    Project chopper

    Given that info it does sound like you need some support down there. I'd expect a permanent curve to set in before long without it. It seems like a good place to make a composite. ie reinforce with ally or carbon tube rather than steel and glue it in. You'd get some of the give of the steel with...

    Project chopper

    Are you certain it's the forks that flex or is it the main chassis or a bit of both? It's hard to see the lower fork mount but it looks fairly flimsy with scope to give.

    Will the nuts hold the front wheel in those dropouts with them facing largely uphill?

    Building a Pedicab / Family 'car'

    Point 2 in your first post. The rear axle may not unbolt to get it flat. It's possibly welded on. I suspect that you may get something like a rickshaw built closer to the end of your year there than the beginning. You'll need to make a lot of parts and find a lot on a small island with little...

    DIY battery

    That's a good price for the power they give.

    Looking for help on ideas on wheel and hub sizes for a trike project

    The bigger wheels will be better for mounting and dismounting curbs but will be weaker for cornering. No bike wheel is expected to take any cornering stress and the bigger the wheel the larger the lever on the rims. If you corner hard there's a good chance that 24 " or bigger will simply fold...

    My life with Python trikes Mk1 , Mk1.5 , Mk2 ?

    I have them on my tilter and it's a perfectly easy and intuitive set-up to use. Don't forget that because you are leaning the amount of turn is very little.

    Pull behind camper

    Weight is a big issue for anything I pedal any distance and every journey home is uphill as I live at the top of one. I'm sure it would be more enjoyable to live in a valley and have the homeward journey downhill.

    You can have your cake AND eat it. Put the bars on the non-tilting part, pivot them at the bottom and run rods to the steering part. Balance and steering, dual purpose bars. It doesn't have to be either / or.

    Pull behind camper

    I suppose you can accept the extra weight penalty for the extra luxury being in one of the flattest places on Earth.:)

    Pull behind camper

    I assume the Dream Box is a converted car roof box which is quite a good place to start from IMO if building your own. It would be hard to make anything as big any lighter or as waterproof and the side material ought to be easy enough to make plus the added bonus of not being overly affected by...

    Warrior trike frame jigs

    When welding the uprights to the arms slot some studding through the axle mounts to keep the two wheels in the same plane.

    Warrior trike- 1st build

    You are going to swap mid drive units for winter and summer!? Seems an odd thing to do but I'll look forward to you making one.
